In the IMAP protocol folder names are always passed over the network in
a modified version of UTF-7 (mUTF-7). This encoding uses only ASCII
compatible bytes.

I don't know what getmail 5 and 6 do internally, but there's more than
one way it might be done. It could store the names as mUTF-7 ASCII
strings. It could store them in a more conventional encoding, such as
UTF-8, and convert to mUTF-7 as necessary.
